Input current on Multiplus II is always 0 A.

Hello, I have an active input connected to the Multiplus II but the multiplus does not read the input current. It does read the input voltage and output current. See image below:1704981247208.png

Why could this be? Could it be that the current transducer is broken?

Best regards

@sebastia@phoenixone.co

Has it connected (closed its relay) on the input?

How is it programmed? With virtual switch (ve config) or maybe Conditional AC connect (Victron connect)

A simpler check on the GX under

devices list - inverter - switch state

and see if it is 'inverter only' set there.

We had the same issue with our Multiplus-ii configuration and it turn out to be caused by a faulty external current jack on the unit. New units have an audio jack, older ones had a terminal block to connect an external current sense coil to. When nothing is plugged into the jack, a set of contacts close to tell the Multiplus to make use of its internal current sense. Some other users found that by inserting and removing an audio plug several times would result in closing this connection again. This did fix our issue, and I would like Victron to create a jumper plug to ensure this problem doesn't repeat in the future.
